Systems, methods, and storage media for testing local loops of telecommunications networks

A method of automatically testing local loops of telecommunications networks, the method comprising:

• obtaining, at a computing system, attenuation data collected by a computing device coupled with a local loop of a telecommunications network, the attenuation data including a first attenuation value for a first tone carried by the local loop, the first attenuation value indicating attenuation for the first tone, and a second attenuation value for a second tone carried by the local loop, the second attenuation indicating attenuation for the second tone, wherein the local loop has a line type and a line length;
• calculating, at the computing system, a first attenuation threshold based on the line type, the line length, and a frequency of the first tone and calculate a second attenuation threshold based on the line type, the line length, and a frequency of the second tone, the first attenuation threshold indicating an allowable attenuation for the first tone for delivering a service over the local loop and the second attenuation threshold indicated an allowable attenuation for the second tone for delivering the service over the local loop;
• and
• determining, using the computing system, at least one of the first attenuation value exceeds the first attenuation threshold or the second attenuation value exceeds the second attenuation threshold.

A tangible, non-transitory, computer-readable media having instructions encoded thereon, the instructions, when executed by a processor are operable to:

• obtain attenuation data collected by a computing device communicatively coupled with a local loop of a telecommunications network, the attenuation data including a first attenuation value for a first tone carried by the local loop, the first attenuation value indicating attenuation for the first tone, and a second attenuation value for a second tone carried by the local loop, the second attenuation indicating attenuation for the second tone, wherein the local loop has a line type and a line length;
• calculate a first attenuation threshold based on a line type, the line type, the line length, and a frequency of the first tone and calculate a second attenuation threshold based on the line type, the line length, and a frequency of the second tone, the first attenuation threshold indicating an allowable attenuation for the first tone for delivering a service over the local loop and the second attenuation threshold indicated an allowable attenuation for the second tone for delivering the service over the local loop;
• and
• determine whether at least one of the first attenuation value exceeds the first attenuation threshold or the second attenuation value exceeds the second attenuation threshold.
